Spice and Wolf - A very good novel, completed as well. Hakomari - A very good novel, completed as well. I wonder if these match your preferences. Edit:If you need links for download pm me.
It is actually good ? I'm scared of big booby one-sans and comical monsters just "Ara-ara~" and "Gotcha, bitch!!" all the time.
Despair ending? It has 20 volumes, and the ending is well done. If you want a spoiler Spoiler It's a happy ending
It was Spoiler: Spoiler Some vague scenes of future about MC eventually dying of old age and Horo walking into forest back to her loneliness. , that is quite a Despair Ending for a romance story.
Nothing of that sort. There is a sequel as well but don't even see illustrations of that because it has major spoilers like huge spoilers. Edit: I don't even remember such a scene in the anime, have to rewatch it some time.
well for me, it's good The story actually have ghost and no face slapping scene, only face hammering scene, literally..
